What will I need in a Pigeon loft?? New to Pigeons.

Well my DH said tonight that he wants to build something..... is feeling the urge to cut and saw and glue and nail things together... LMAO Soooooooooo .... I REALLY want a small Pigeon loft (is that the right term?) so that I can get this beautiful trio of Figuritas (sp?) that I saw. They are a smaller breed. So I don't need anything HUGE.

I want something for outside, nice and sturdy but dainty and decorative......

I'll Google it too... but I am wondering, all you Pigeon folks.....

WHAT should I include in this structure? What will they need? I live in MI. It will get cold in the winter... though the guy assures me that they need no special treatment. I am green to the whole thing and have no idea what a pigeon enclosure should have or not have.

Also, any pics of cute little lofts is appreciated to get my creative juices flowing!
